Information

Compared with single-stage pumps, the difference is that multi-stage pumps have more than two impellers, which can absorb and press water in multiple stages, so as to raise the water to a very high position, and the head can be increased or decreased according to needs. The number of stages of the pump impeller. Multi-stage pumps are mainly used for mine drainage, city and factory water supply, and are rarely used for agricultural irrigation. They are only suitable for lifting water in high-lift, low-flow high mountainous areas to solve the difficulty of drinking water for humans and animals.

Single Stage Centrifugal Pump

1. A single-stage pump refers to a pump with only one impeller, and the maximum lift is only 125 meters;
2. A multi-stage pump refers to a pump with two or more impellers, which can absorb and press water in multiple stages, so as to raise the water to a very high position. The head can be increased or decreased according to the needs of the pump impeller. The number of stages; multi-stage pumps can be equipped with four-stage motors by increasing the number of impellers when the head of a single-stage pump needs to be equipped with two-stage motors, so as to improve the service life of the pump and reduce the noise of the unit.
3. When the actual head of the pump is less than 125 meters, the choice of single-stage pump or multi-stage pump can be comprehensively considered according to the pump room area, pump price (multi-stage pumps are generally higher than single-stage pumps), and other factors.
